Utah State Route 159
state highway in Millard County, Utah, United States
State Route 159 (SR-159) is a state highway in west-central Utah that runs from the junction of SR-21 in Garrison to US-6/US-50 8 miles (13 km) to the north near Border by the Nevada border. There are no junctions with any other state highways along SR-159.
Route description
This short highway is mainly used as a cutoff for local Snake Valley residents between Garrison (and SR-21) and the main road in the valley, US-6/50. Motorists traveling from the south to the east, and vice versa, use the SR-159 cutoff. The road does "continue" north of US-6/50 as a dirt road, known commonly as the "Gandy Road." This road travels up Snake Valley toward Gandy, Callao, and eventually to Wendover.
History
